More recently, in a cheeky Instagram photo posted on 12 April, Michelle swaps places with her dentist and sits in the dreaded chair while the former Corrie star checks out his teeth.

In what appears to be a running joke between them about Michelle not brushing her teeth twice a day - day and night - she asks him to open his mouth and then says he’s got damage to one of his lower right teeth.

Then she berates him to camera, shouting: ‘Brush twice a day. Always twice a day, brush regularly, Luk,’ before asking him to spit out.
